Game of Thrones fans may agree that the world of the HBO show is complicated and sometimes even confusing. While fans of this drama fantasy are gearing up for the series finale, some of the devotees are re-watching the show to refresh their memory.

In one such instance, a fan watching the pilot episode of the television series noticed something out of place and he was quick to share it with others. In the brief clip of the scene posted on Twitter by Kevin Biegel, an unknown man walks behind Jamie Lannister, wearing what appears to be a long Patagonia jacket, blue denim jeans and short dark boots.

Considering Game of Thrones is set in a period resembling medieval times, fans were amused to find the background character's modern choice of clothing. Several Twitter users noticed that he looks an awful lot like Bucky Barnes aka Winter soldier from Marvel Cinematic Universe, hinting at time travel theory.

Instead of being killed during the snap the winter soldier apparently went to a different dimension.

“That is Bucky Barnes. Now we know where the snap’d ended up,” joked a fan, making a reference to the ending of Avengers: Infinity War.

Also amusing that he looks kinda like The Winter Soldier. HE'S THERE TO KILL SOMEONE.
